[0020] The following further elaborates the present utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0021] An embodiment of the present utility model relates to an automobile grille structure for reducing flash, as Figures 1-7 shown, which includes an automobile grille 100. An assembly opening 200 is formed on the automobile grille 100. The shape of the assembly opening 200 is a rectangular through-hole. Three buckle structures 300 are arranged on the inner wall of one side of the assembly opening 200. Avoidance grooves 201 that are recessed inward are formed on the inner wall of the assembly opening 200 between every two adjacent buckle structures 300. A flanging structure 202 that extends downward is provided on the avoidance groove 201 close to one side of the assembly opening 200. A buckle matching portion 400 is provided on the automobile grille 100 close to the other side of the assembly opening 200. The lower end of the flanging structure 202 is flush with the lower end of the buckle matching portion 400.

[0022] The cross-sectional structure at the clamping hole of the traditional product is as Figure 5 shown, and the parting line of the die structure corresponding to this product structure is as Figure 7 shown. The parting line at the avoidance groove 201 is composed of L1 and L2. The parting surfaces of the die moving and fixed dies where the L1 parting line is located are in flat contact and seal the glue. The parting surfaces of the die moving and fixed dies where the L2 parting line is located are in side rubbing contact and seal the glue. During the production process, due to the high-frequency friction and collision between the moving and fixed dies on the parting surface where L2 is located, the parting surface where L2 is located is prone to wear, thus causing the melt plastic to overflow and generating flash problems.

[0023] The cross-sectional structure of the present utility model is as Figure 4 shown. The flanging structure 202 with a thickness of A and a height of B extends from the avoidance groove 201 close to one side of the assembly opening 200. Without affecting the assembly relationship of the automobile grille 100, the value of A is usually taken as 0.2 - 0.3 mm, and the value of B is preferably such that the lower end of the flanging structure 202 is flush with the lower end of the buckle matching portion 400. The die parting structure corresponding to the product structure of the present utility model is as Figure 6 shown. Figure 6 At the avoidance groove 201 in

[0024] is L1, that is, compared with the traditional die structure, the parting surface where the L2 parting line is located is omitted, and the action of mutual friction between the side parting surfaces of the moving and fixed dies of L2 is avoided. Only the flat contact and glue sealing of the moving and fixed dies of L1 exist, thus effectively avoiding the problem of flash overflow around the parting surface where L2 is located.

[0025] Further, a stepped surface 101 is provided on the upper end of the vehicle grille 100 on the other side of the assembly port 200. The stepped surface 101 is provided for fitting with the bright strip to reduce the position change after the bright strip is installed.

[0026] Specifically, in this embodiment, the number of the buckle structures 300 is 3, and the number of the avoidance grooves 201 is 2. The specific number can be increased or decreased according to actual requirements to ensure that the product meets the requirements.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0028] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures" afterwards. Thus, the exemplary term "above..." can include both orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations are made for the spatial relative descriptions used here.

[0029] In addition, it should be noted that the use of words such as "first", "second" to limit the components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meaning. Therefore, it should not be construed as limiting the protection scope of the present invention.

[0030] The above has introduced in detail a car grille structure for reducing flash. In this article, specific examples are used to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation of the present application.
